This one is just an oversight, it can be changed to fcntl.h. There is 
another one in genSolarisConstants.c that can also be changed but that 
one is probably not an issue for AIX as that source file is Solaris 
specific.

I've created a bug to track this:
7100054: (porting) Native code should include fcntl.h and unistd.h 
rather than sys/fcntl.h and sys/unistd.h
